Which of the following represents the equation for the position-time relation in uniformly accelerated motion?
A2as = v^2 - u^2
Bv = u + at
Cs = ut + (1/2)at^2
Da = (v - u)/t
Answer & Solution
Correct answer: C. s = ut + (1/2)at^2
1. The position-time relation links displacement s with time t.
2. It is s = ut + (1/2)at^2.
3. v = u + at is velocity-time, and 2as = v^2 - u^2 is the velocity-position relation.
